The people who supply food coupons to the annex are arrested. The residents’ only alternative is the black-market ration books they have, and the food they must eat is horrible. Miep gets sick with the flu, and Jan says it is impossible to see a doctor. Anne says that she is more restless than Peter because he has his own room, while she has to share one with Mr. Dussel.

Anne and Margot are both growing annoyed with their parents. Anne complains that her parents are not open about sex and sexuality. She and Margot exchange letters. Margot writes that she is somewhat jealous of Anne’s relationship with Peter, but only because she also wants someone with whom she can share her feelings. Anne is growing happier with her relationship with Peter but cannot fathom ever marrying him.

Anne decides to ask Peter about sex, since she believes “he knows everything,” and later she talks to Margot in the bathroom. Peter overhears them and thinks Anne only spoke to him to tease him, but she tells him it is untrue. Anne says she would like to ask if Peter knows about female genitalia, and she writes a description of her own anatomy in her diary.

Anne’s mother forbids Anne from going up to see Peter because Mrs. van Daan is jealous. Peter invites Margot to come upstairs with Anne. Listening to the radio at the end of March, Anne hears a member of the Dutch government in exile propose a collection of Dutch people’s diaries and letters after the war. Anne writes that everyone in the annex immediately thought of her diary. She wonders what would happen if she published a novel about the annex, and thinks that ten years after the war people would find her diary very interesting. To pass the time, Anne continues writing stories and describes some of them in her diary. She also writes about her hobbies, such as genealogy and mythology. Food is growing scarce and there are no vegetables left.

Anne is talking to Peter one night when another break-in occurs. Mr. van Daan tries to scare the burglars away by shouting “Police!” but the residents see someone shine a flashlight through a gap in the wall and hear footsteps running away. Anne is terrified, thinking the Gestapo is about to come for them. The residents lie on the floor, petrified, and hear footsteps on the stairs and a rattling at the bookcase that hides the door to the annex. The noises stop but someone has left the light in front of the bookcase on.

Mrs. van Daan worries about the police finding the radio downstairs, and Otto Frank worries they will find Anne’s diary. Anne writes, “If my diary goes, I go too.” The adults phone Mr. Kleiman and wait in suspense until a knock comes on the door. They cry with relief when they see it is only Jan and Miep. Anne wonders why the Jews have been singled out for death. She decides that after the war she will become a Dutch citizen because she loves Holland and the Dutch. She writes, “If God lets me live . . . I’ll make my voice heard.”
